ROTARY MOTOR.

Specification of Letters Patent.

Patented Aug. .3, 1921.

App1ication filed May 18, 1920. Serial No. 382,374.

To all whom it may concern:

Be it known that I, Gnone NoLmrANN, a citizen of the German Republic,residing at Calle Maipii 671, Buenos Aires, Argentine Republic, haveinvented new and useful Improvements in a Rotary Motor, of which thefollowing is a specification.

This invention has for its object an improved rotary motor, a mainfeature of which is the simplicity of its construction, substantiallyconsisting of a fly wheel of suitable dimensions, according to the speedand degree of power to be developed, whose periphery is combined withone or more propelling chambers and is provided with a series ofprojecting paddles, adapted to move radially under the action of a cam.

The novel motor according to this invention may be operated by steam,explosion gases, water, compressed air, etc., being also adapted tooperate as an air compressor or as a simple lifting and forcing pump.

Owing to the limited space occupied by the structure, as well as to itssimple construction and large yield of motive power developed thereby,this motor offers considerable advantages over the constructionsactually known.

The direction of running may be reversed, by simply reversing thedirection of circulation of the operating fluid.

For the better understanding of this de scription, illustrative detaileddrawings have been annexed thereto, wherein Figure 1 is a view in frontelevation of a rotary motor or engine constructed in accordance with myinvention.

Fig. 2 is a view of the same motor, partially in section and showingthree propelling chambers.

Fig. 3 is a sectional elevation on the line A-B of Fig. 1.

In said drawings, 1 is the motor wheel, mounted on the shaft 2,supported in turn on suitable brackets 3 which may be of any convenientshape and dimensions. To said motor wheel is secured a series of paddles4, adapted to operate in recesses or cavities formed within the wheel,each of the paddles being fixed to a stem 5 which tends to move towardthe center of the wheel under the action of a spring 6 and carrying onits end a roller 7, mounted to move in engagement with a cam 8, as tocause by this means the radial movement of said paddles or plates.

In combination with the motor wheel 1 are provided one or morepropelling chambers 9, suitably retained in position, into which openthe pipes 10 and 11, adapted to be used alternately for the admission orexhaust oi the operating fluid, according to the direction of running ofthe motor.

Each of the chambers or compartn'ients fits well with its end in theperiphery 01. the fly wheel and with its sides to the rims ot the same,being maintained in this position by means of the radial arms 12, thelength. of which may be adjusted by means of nuts 13. Between the motorwheel and the chambers is left a space extending through a smaller orlarger sector, according to the number of paddles used on the motorwheel.

It will be readily understood that the direction of running of the wheelwill depend on the direction given to the operating fluid.

Referring to Fig. 2, it will clearly be seen that when the fluid entersin the direction. indicated by the arrows, the paddle 4% which closesthe space between the chamber 9 and the wheel 1, will be propelled so asto cause the wheel to rotate until the next following paddle is caughtby the fluid and operated in substitution of the foregoing one, therebyproducing the continuous rotary motion of the wheel.

Said paddles, on being submitted to the propelling force of the steam,air, etc., when entering into the chamber or compartment,

1 will be lifted by the action of the cam 8 and will descend at theinstant in which its operation is replaced by that of the followingpaddle, so as to allow of the exhaust to take place without interferingwith its passage at the point of fitting between the chamber and thewheel.

It will be apparent that, two or more of the above described motorwheels may be coupled to the same shaft and that the number ofpropelling chambers may be increased according to the diameter andnumber of paddles of each of said wheels.

I now declare that what I claim as new and desire to secure by LettersPatent, is

A rotary motor comprising a fly wheel having spokes, flanges on. eachside of the wheel rim forming an annular ch amber, said rim projectinglaterally at one side of the spokes and having pockets formed therein,blades in said pockets, stems on the blades projecting from said pocketscentrally of the channel and at one side of the spokes, springs andradially adjustable rods connecting the on the stems normallyretractingfthe blades, channel to the hub. a stationary cam at thecenter 0 the wheel over which the ends of the stems travel, a GEORGNOLLMANN' 5 detachable steam channel extending over a Witnesses:

portion of the rim and having sides fitting A. L. BELKE, over theflanges of the rim, a. stationary hub, H. CORIANO.
